As a scientist who comes from the dessicated drylands of the unforgiving Kerio Valley, where severe drought can mean loss of life through loss of food and animals, what comes first is food security… I could start to give something back to the community… It’s been a dream finally coming true.” – Paul Kimurto, Senior Lecturer and Professor in Crop Physiology and Breeding, Egerton University, Kenya

As a son of peasant farmers growing up in a humble home in the Rift Valley of Kenya, agriculture was, for Paul Kimurto (pictured above), not merely a vocation but a way of life: “Coming from a pastoral community, I used to take care of the cattle and other animals for my father. In my community livestock is key, as is farming of food crops such as maize, beans and finger millet.”

Covering some six kilometres each day by foot to bolster this invaluable home education with rural school, an affiliation and ever-blossoming passion for agriculture soon led him to Kenya’s Egerton University.

There, Paul excelled throughout his undergraduate course in Agricultural Sciences, and was thus hand-picked by his professors to proceed to a Master’s degree in Crop Sciences at the self-same university, before going on to obtain a German Academic Exchange Service (DAAD) scholarship to undertake a ‘sandwich’ PhD in Plant Physiology and Crop Breeding at Egerton University and the Leibniz Institute for AgriculturalEngineering (ATB) in Berlin, Germany.

… what comes first is food security… offering alternative drought-tolerant crops… is a dream finally coming true!… GCP turned out to be one of the best and biggest relationships and collaborations we’ve had.”

Local action, global interactionWith his freshly minted PhD, Paul returned to Egerton’s faculty staff and steadily climbed the ranks to his current position as Professor and Senior Lecturer in Crop Physiology and Breeding at Egerton’s Crop Sciences Department. Yet for Paul, motivating this professional ascent throughout has been one fundamental factor: “As a scientist who comes from a dryland area of Kerio valley, where severe drought can mean loss of food and animals, what comes first is food security,” Paul explains. “Throughout the course of my time at Egerton, as I began to understand how to develop and evaluate core crop varieties, I could start to give something back to the community, by offering alternative drought-tolerant crops like chickpeas, pigeonpeas, groundnuts and finger millet that provide farmers and their families with food security. It’s been a dream finally coming true.”

And thus one of academia’s true young-guns was forged: with an insatiable thirst for moving his discipline forward by seeking out innovative solutions to real problems on the ground, Paul focused on casting his net wide and enhancing manpower through effective collaborations, having already established fruitful working relationships with the International Maize and Wheat Improvement Center (CIMMYT), the (then) Kenya Agricultural Research Institute (KARI) and the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in earlier collaborative projects on dryland crops in Kenya. It was this strategy that paved the way towards teaming up with GCP, when, in 2008, Paul and his team were commissioned to lead the chickpea work in Kenya for the GCP Tropical Legumes I project (TLI), with local efforts being supported by colleagues at ICRISAT, and friends down the road at KARI undertaking the bean work of the project. Climbing aboard the GCP ship, Paul reveals, was a move worth making: “Our initial engagement with GCP started out as a small idea, but in fact, GCP turned out to be one of the best and biggest relationships and collaborations we’ve had.”

…GCP is people-oriented, and people-driven”

Power to the people!The success behind this happy marriage, Paul believes, is really quite simple: “The big difference with GCP is that it is people-oriented, and people-driven,” Paul observes, continuing: “GCP is building individuals: people with ideas become equipped to develop professionally.” Paul elaborates further: “I wasn’t very good at molecular breeding before, but now, my colleagues and I have been trained in molecular tools, genotyping, data management, and in the application of molecular tools in the improvement of chickpeas through GCP’s Integrated Breeding Multiyear Course. This has opened up opportunities for our local chickpea research community and beyond, which, without GCP’s support, would not have been possible for us as a developing-country institution.”

Passionate about his teaching and research work, it’s a journey of discovery Paul is excited to have shares with others: “My co-workers and PhD students have all benefitted. Technicians have been trained abroad. All my colleagues have a story to tell,” he says. And whilst these stories may range from examples of access to training, infrastructure or genomic resources, the common thread throughout is one of self-empowerment and the new-found ability to move forward as a team: “Thanks to our involvement with the GCP’s Genotyping Support Service, we now know how to send plant DNA to the some of the world’s best labs and to analyse the results, as well as to plan for the costs. With training in how to prepare the fields, and infrastructure such as irrigation systems and resources such as tablets, which help us to take data in the field more precisely, we are now generating accurate research results leading to high-quality data.”

The links we’ve established have been tremendous, and we think many of them should be long-lasting too: even without GCP“

Teamwork, international connections and science with a strong sense of mission
Teaming up with other like-minded colleagues from crème de la crème institutions worldwide has also been vital, he explains: “The links we’ve established have been tremendous, and we think many of them should be long-lasting too: even without GCP, we should be able to sustain collaboration with KBioscience [now LGC Genomics] or ICRISAT for example, for genotyping or analysing our data.” He holds similar views towards GCP’s Integrated Breeding Platform (IBP): “IBP is one of the ideas which we think, even after GCP’s exit in December 2014, will continue to support our breeding programmes. My colleagues and I consult IBP regularly for a range of aspects, from markers to protocols to germplasm and the helpdesk, as well as for contacts and content available via the IBP Communities of Practice.” Paul’s colleagues are Richard Mulwa, Alice Kosgei, Serah Songok, Moses Oyier, Paul Korir, Bernard Towett, Nancy Njogu and Lilian Samoei. Paul continues: “We’ve also been encouraging our regional partners to register on IBP – I believe colleagues across Eastern and Central Africa could benefit from this one-stop shop.”

Yet whilst talking animatedly about the greater sophistication and accuracy in his work granted as a result of new infrastructure and the wealth of molecular tools and techniques now available to him and his team, at no point do Paul’s attentions stray from the all-important bigger picture of food security and sustainable livelihoods for his local community: “When we started in 2008, chickpeas were known as a minor crop, with little economic value, and in the unfavoured cluster termed ‘orphan crops’ in research. Since intensifying our work on the crop through TLI, we have gradually seen chickpeas become, thanks to their relative resilience against drought, an important rotational crop after maize and wheat during the short rains in dry highlands of Rift valley and also in the harsh environments of the Kerio Valley and swathes of Eastern Kenya.”

This GCP-funded weather station is at Koibatek Farmers Training Centre.

Having such a back-up in place can prove a vital lifeline to farmers, Paul explains, particularly during moments of crisis, citing the 2011–2012 outbreak of the maize lethal necrosis (MLN) disease which wiped out all the maize throughout Kenya’s Bomet County, where Paul, Richard, Bernard and their team had been working on the chickpea reference set. Those farmers who had planted chickpeas – Paul recalls Toroto and Absalom as two such fortunate souls – were food-secure. Moreover, GCP support for infrastructure such as a weather station have helped farmers in Koibatek County to predict weather patterns and anticipate rainfall, whilst an irrigation system in the area is being used by the Kenyan Ministry of Agriculture to develop improved seed varieties and pasture for farmers.

The science behind the scenes and the resultant products are of course not to be underestimated: in collaboration with ICRISAT, Paul and his team released four drought-resistant chickpea varieties in Kenya in 2012, with the self-same collaboration leading to the integration of at least four varieties of the crop using marker-assisted backcrossing, one of which is in the final stages and soon to be released for field testing. With GCP having contributed to the recent sequencing of the chickpea genome, Paul and his colleagues are now looking to up their game by possibly moving into work on biotic stresses in the crop such as diseases, an ambitious step which Paul feels confident can be realised through effective collaboration, with potential contenders for the mission including ICRISAT (for molecular markers), Ethiopia and Spain (for germplasm) and researchers at the International Center for Agricultural Research in the Dry Areas (ICARDA) for germplasm. Paul first established contact with all of these partners during GCP meetings.

By coming together, pooling skills from biotechnology, agronomy, breeding, statistics and other disciplines, we are stronger as a unit and better equipped to offer solutions to African agriculture and to the current challenges we face.”

Links that flower, a roving eye, and the heat is on!
In the meantime, the fruits of other links established since joining the GCP family are already starting to blossom. For example, TLI products such as certified seeds of chickpea varieties being released in Kenya – and in particular the yet-to-be-released marker-assisted breeding chickpea lines which are currently under evaluation – caught the eye of George Birigwa, Senior Programme Officer at the Program for Africa’s Seed Systems (PASS) initiative of the Alliance for a Green Revolution in Africa (AGRA), which is now supporting the work being undertaken by Paul and his team through the Egerton Seed Unit and Variety Development Centre (of which Paul is currently Director) at the Agro-Based Science Park.

Yet whilst Paul’s love affair with chickpeas has evidently been going from strength to strength, he has also enjoyed a healthy courtship with research in other legumes: by engaging in a Pan-African Bean Research Alliance (PABRA) bean project coordinated by the International Center for Tropical Agriculture (CIAT), Paul and his team were able to release and commercialise three bean varieties which are currently in farmers’ fields in Kenya.

With so many pots on the boil, the heat is certainly on in Paul’s research kitchen, yet he continues to navigate such daily challenges with characteristic aplomb. As a proven leader of change in his community and a ‘ can-do, make-it-happen’ kind of guy, he is driving research forward to ensure that both his school and discipline remain fresh and relevant – and he’s taking his colleagues, students and local community along with him every step of the way.

Indeed, rallying the troops for the greater good is an achievement he values dearly: “By coming together, pooling skills from biotechnology, agronomy, breeding, statistics and other disciplines, we are stronger as a unit and better equipped to offer solutions to African agriculture and to the current challenges we face,” he affirms. This is a crusade he has no plans to abandon any time soon, as revealed when quizzed on his future aspirations and career plans: “My aim is to continue nurturing my current achievements, and to work harder to improve my abilities and provide opportunities for my institution, colleagues, students, friends and people within the region.”

With the chickpea research community thriving, resulting in concrete food-security alternatives, we raise a toast to Paul Kimurto and his chickpea champions!

Friendship and trust at the heart of sorghum research

…benefits to humanity are the real driver of the work.”

Andrew Borrell (pictured) is a man who loves his work – a search for a holy grail of sorts for the grain of his choice – sorghum.

Based at the University of Queensland, Australia, Andrew is co-Principal Investigator with David Jordan for a GCP-funded project developing drought-adapted sorghum for Africa and Australia. And Andrew is passionate not just about the potential of sorghum, but also about the cross-continental relationships that underpin his research team. These friendships, says Andrew, are the glue that hold his team together and make it work better.

The year 2013 was particularly exciting. After almost five years working with African plant breeders to improve genetic material, field trials were up and running at 12 sites across East and West Africa. Fastforward to 2015 and glad tidings for the New Year! Andrew and his team now have preliminary evidence that the drought-tolerant ‘stay-green’ trait enhances grain size and yield in some of the target countries in Africa for which data have already been analysed.

What Andrew hopes to see is more genetic diversity, not just for diversity’s sake but put to use in farmers’ fields to enhance yield during drought. This means more food, fodder and other sorghum by-products such as stems for construction. These benefits to humanity are, he says, the real driver of the work his team does.

So what are the wonders of ‘stay-green’? Waxing lyrical…

The sought-after ‘stay-green’ trait that Andrew and his team are so interested in describes the phenotype – what the plant looks like. It simply means that when drought strikes, sorghum plants with this trait remain leafy and green during the grain-filling period – a critical time when the plant’s water is channelled to developing healthy panicles of grain.

So, what makes these plants remain healthy when others are losing their leaves? Why do they wax while others wane? The answer, says Andrew, is twofold, and is all to do with water supply and demand, and more and less. Firstly, there is some evidence that the roots of the stay-green plants penetrate deeper into the soil, tapping into more water supply. Secondly, plants with the stay-green trait have a smaller leaf canopy which means less water demand by the plant before flowering, leaving more water for grain-filling after flowering.

Staying power and stover are also part of the story. According to Andrew, “Plants with the stay-green trait produce more grain in dry conditions, have stronger stems so they don’t fall over, and often have larger grains. And it’s not just about grain alone: stay-green also improves the quality of the stover left in the field after harvest, which serves as animal feed.”

Another key feature of the stay-green trait in sorghum is that it is not just a fair-weather friend: it works well in wet as well as dry conditions. “All the evidence we’ve got suggests that you get a benefit under tough conditions but very little penalty under good conditions,” says Andrew.

…the process is synergistic and we do something that’s better than any of us could do alone.”

Safari from Down Under to Africa: East and West, and home are all best

For Andrew and his co-Principal Investigator, David Jordan, the GCP project is the first time they have been involved in improving sorghum in Africa. The two scientists work with sorghum improvement teams in six African countries: Mali, Burkina Faso and Niger in the west, and, Ethiopia, Kenya and Sudan in the east. By crossing African and Australian sorghum, the teams have developed the lines now being field-tested in all the six countries.

(3) Clement Kamau (Kenya, left) and Andrew Borrell (Australia, right) visiting the seed store at the Kenya Agricultural Research Institute (KARI) in Katumani, Kenya.

According to Andrew, the collaboration with African scientists is “a bit like a group of friends using science to combat hunger. That’s probably been the biggest advantage of GCP,” adds Andrew. “Bringing people together for something we are all passionate about.”

There’s another collaborative element to the project too. As well as improving and testing plant material, the Australian contingent hosts African scientists on three-week training sessions. “We span a whole range of research topics and techniques,” explains Andrew. “We learn a lot from them too – their local expertise on soil, crops and climate. Hopefully the process is synergistic and we do something that’s better than any of us could do alone.”

Andrew says that working personally with plant breeders from Africa has made all the difference to the project. “Once colleagues from overseas come into your country, you develop real friendships. They know your families, they know what you do, and that’s very important in building relationships and trust that make the whole thing work.”

It wasn’t all work and there was clearly also time to play, as we can see here, Sidi Coulibaly and Niaba Teme from Mali visit the Borrell family in Queensland, Australia.

As Andrew and his team wait to see how their field experiments in Africa turn out, they know that this is not the end of the story. In fact, it is only the beginning. Once tested, the germplasm will provide genetic diversity for future breeding programmes in Africa.

And the research collaboration between Australia and Africa won’t end when GCP funding runs out and GCP sunsets. For example, in addition to the GCP project, David Jordan has secured significant funding from the Bill & Melinda Gates Foundation for another four years’ sorghum research in Ethiopia. Plus, Andrew and Kassahun Banttea, a colleague from Jimma University, have also just been awarded a PEARL grant from the Foundation to assess the sorghum germplasm collection in Ethiopia for drought-adaptation traits.

We wish this ‘stay-evergreen’ team well in their current and future ventures. More sorghum ‘stickability’ and staying power to them! May they find the proverbial pot of gold at the end of the rainbow.

In recognition of the International Day for the Eradication of Poverty, October 17th, we are reflecting on what poverty means, how crop breeding helps eradicate poverty and transform lives, and how we have tried to maximise and measure those impacts.

In the early days of GCP, we were largely on uncharted seas and needed to chart a course to where our efforts would have the greatest impact, a process documented in our Pathways to impact brief No 1: Where in the world do we start? Instead of using a monetary definition of poverty, since this varies so widely between places and contexts, we took a different approach. As an indicator of true poverty, we used data on the number of stunted – ie, severely malnourished – children, overlaying this on maps showing where drought was most likely to occur. Our thinking was clear and simple: poverty + drought = where GCP needed to be.

Whatever else you may think they may lack, these children in Sibi village, Burkina Faso, definitely have verve, and look full of the energy they need to play!

Drought routinely reduces harvests, and can be catastrophic. For example, nearly half (40 percent) of Africa’s maize-lands face occasional drought, reducing yields by between 10 and 25 percent, while a quarter suffers frequent drought, with overall losses of up to half the harvest – and total losses for some individual farmers. With climate change making droughts ever more common, drought was a natural priority for GCP from its inception.

Drought-tolerant crops are therefore the most important focus for the breeders of the GCP family, though not an exclusive one. Other key traits our breeders consider include resistance to pests and diseases and nutritional fortification, depending on the crop and location – and of course all varieties should yield well in good years too. Resilient improved varieties are particularly important for the poorest farmers, as they do not usually have access to measures such as irrigation or pesticides to combat environmental menaces. Typically, the poorest farmers also live in the most drought-prone drylands. Helping poor farmers to reap consistently abundant nutritious harvests means more food for their families and often a surplus to sell –reducing child malnourishment, and poverty in general.

Together we stand

The theme of the International Day for the Eradication of Poverty 2014 is Leave no one behind: think, decide and act together against extreme poverty, and it is one that echoes beautifully with the ethos of GCP. Collaboration and partnership have always been hallmarks of our approach, particularly in terms of empowering researchers in developing countries to implement – and lead – cutting-edge science. You can find a wealth of posts on our blog about our partnerships and the ‘GCP spirit’.

Collaboration is particularly important in crop breeding because one crop is often faced by all kinds of threats at once – a selection from the world’s least tasty smorgasbord of drought, heat, waterlogging pests, diseases, soil infertility, and much more. It is likely to be of no use breeding a super-crop that goes untouched by disease if it turns up its toes after a few dry days, or if no one likes the taste. That means researchers with different areas of expertise need to work together – and with farmers and extensionists too. Read the case for collective action in our Pathways to impact brief No 2: A call for collective action in agricultural research.

Impact by the numbers

GCP believes that using marker-assisted breeding (a range of efficient crop-breeding approaches that use genetic information to work out which plants have useful traits) to create improved varieties faster and more effectively is worth its extra cost, and has a real impact on farmers’ incomes. This cannot be taken for granted however, so get an introduction to the numerical approach in our Pathways to impact brief No 3: Molecular and conventional breeding through an economic lens. Our study found that women in Nigeria reported increased household incomes from growing improved cassava varieties, but also more time spent on cassava-related tasks – emphasising the need for researchers to be aware of the characteristics farmers – in this case predominantly women – value.

Hard at work, a boy helps to peel a mountain of cassava in Nigeria.

As we mark this year’s International Day for the Eradication of Poverty, we at GCP are proud to be contributing to the eradication of poverty by creating partnerships, expertise, and ultimately crop varieties that promise abundant harvests for the world’s poorest farmers and their families – helping their children grow up big, strong and free from poverty.

Scouring the planet for breeding solutions

Bindiganavile Vivek

Bindiganavile Vivek (pictured) is a maize breeder working at the International Maize and Wheat Improvement Center (CIMMYT), based in Hyderabad, India. For the past five years, Vivek and his team have been developing drought-tolerant germplasm for Asia using relatively new molecular-breeding approaches – marker-assisted recurrent selection (MARS), applied in a genomewide selection (GWS) mode. Their work in the Asian Maize Drought-Tolerance (AMDROUT) project is implemented through GCP’s Maize Research Initiative, with Vivek as the AMDROUT Principal Investigator.

Driven by consumer demand for drought-tolerant maize varieties in Asia, the AMDROUT research team has focussed on finding suitable drought-tolerant donors from Africa and Mexico. Most of these donors are white-seeded, yet in Asia, market and consumer preferences predominantly favour yellow-seeded maize. Moreover, maize varieties are very site-specific and this poses yet another challenge. Clearly, breeding is needed for any new target environments, all the while also with an eye on pronounced market and consumer preferences.

Stalked by drought, tough to catch, but still the next big thing

Around 80 per cent of the 19 million hectares of maize in South and Southeast Asia is grown under rainfed conditions, and is therefore susceptible to drought, when rains fail. Tackling drought can therefore provide excellent returns to rainfed maize research and development investments. As we shall see later, Vivek and his team have already made significant progress in developing drought-tolerant maize.

The stark reality of drought is illustrated in this warning sign on a desiccated drought-scorched landscape, showing the severity of drought in Asia

But they are after a tough target: drought tolerance is dodgy since it is a highly polygenic trait, making it difficult for plant scientists to pinpoint genes for the trait (see this video with an example from rice in Africa). In other words, to make a plant drought-tolerant, many genes have to be incorporated into a new variety. As one would expect, the degree of difficulty is directly proportional to the number of genes involved. In the private-sector seed industry, MARS (PDF) has been successfully used in achieving rapid progress towards high grain yield under optimal growth conditions. Therefore, a similar approach could be used to speed up the process of introducing drought tolerance into Asian crops – the reason why the technique is now being used by this project.

More than India: the AMDROUT project also comprises research teams in China, Indonesia, Thailand, The Philippines and Vietnam. In this photo taken during the December 2010 annual project meeting in Penang, Malaysia, the AMDROUT team assessed the progress made by each country team, and team members were trained in data management and drought phenotyping. They also realised that there was a need for more training in genomic selection, and did something about it, as we shall see in the next photo. Pictured here, left to right: Luo Liming, Tan jing Li, Villamor Ladia, V Vengadessan, Muhammad Adnan, Le Quy Kha, Pichet Grudloyma, Vivek, IS Singh, Dan Jeffers (back), Eureka Ocampo (front), Amara Traisiri and Van Vuong.

The rise of maize: clear chicken-and-egg sequence…

Vivek says that the area used for growing maize in India has expanded rapidly in recent years. In some areas, maize is in fact displacing sorghum and rice. And the maize juggernaut rolls beyond India to South and Southeast Asia. In Vietnam, for example, the government is actively promoting the expansion of maize acreage, again displacing rice. Other countries involved in the push for maize include China, Indonesia and The Philippines.

So what’s driving this shift in cropping to modern drought-tolerant maize? The curious answer to this question lies in food-chain dynamics. According to Vivek, the dramatic increase in demand for meat – particularly poultry – is the driver, with 70 percent of maize produced going to animal feed, and 70 percent of that going into the poultry sector alone.

GCP gave us a good start… the AMDROUT project laid the foundation for other CIMMYT projects”

Show and tell: posting and sharing dividends

As GCP approaches its sunset in December 2014, Vivek reports that all the AMDROUT milestones have been achieved. Good progress has been made in developing early-generation yellow drought-tolerant inbred lines. The use of MARS by the team – something of a first in the public sector – has proved to be useful. In addition, regional scientists have benefitted from broad training from experts on breeding trial evaluation and genomic selection (photo-story on continuous capacity-building). “GCP gave us a good start. We now need to expand and build on this,” says Vivek.

AMDROUT calls in on Cambridge for capacity building. AMDROUT country partners were at Cambridge University, UK, in March 2013, for training in quantitative genetics, genomic selection and association mapping. This was a second training session for the team, the first having been September 2012 in India. Pictured here, left to right – front row: Sri Sunarti, Neni Iriany, Hongmei Chen; middle row: Ian Mackay (Cambridge), Muhammad Azrai, Le Quy Kha, Artemio Salazar; back row: Roy Efendy, Alison Bentley (who helped organise, run and teach on the course, alongside Ian) and Suriphat Thaitad.AMDROUT country partners are from China’s Yunnan Academy of Agricultural Sciences (YAAS); the Indonesian Cereals Research Institute (ICERI); the Institute of Plant Breeding at the Unversity of Philppines at Los Baños (UPLB); Thailand’s Nakhon Sawan Field Crops Research Center (NSFCRC); Vietnam’s National Maize Research Institute (NMRI); and private-sector seed companies in India, such as Krishidhan Seeds.Curious on who proposed to whom for this AMDROUT–Cambridge get-together? We have the answer: a Cambridge callout announced the training, and AMDROUT answered by calling in, since course topics were directly relevant to AMDROUT’s research approach.

There is now also an International Maize Consortium for Asia (IMIC–Asia), coordinated by CIMMYT, comprising a group of 30 commercial companies (ranging from small to large; local to transnational). Through this consortium, CIMMYT is developing maize hybrids for specific environmental conditions, including drought. IMIC–Asia will channel and deploy the germplasms produced by AMDROUT and other projects, with a view to assuring impact in farmers’ fields.

Overall, Vivek’s experience with GCP has been very positive, with the funding allowing him to focus on the agreed milestones, but with adaptations along the way when need arose: Vivek says that GCP was open and flexible regarding necessary mid-course corrections that the team needed to make in their research.

But what next with GCP coming to a close? Outputs from the AMDROUT project will be further refined, tested and deployed through other projects such as Triple A, thus assuring product sustainability and delivery after GCP winds up.

As our Maize Research Initiative does not have a Product Delivery Coordinator, Vivek graciously stepped in to coordinate the maize research group at our General Research Meeting in 2013, for which we thank him yet again. Below are slides summing up the products from this research, and the status of the projects then.

One of the greatest challenges of our time is growing more crops to feed more people, but using less water

Sorghum is one of the most ‘efficient’ crops in terms of needing less water and nutrients to grow. And although it is naturally well-adapted to sun-scorched drylands, there is still a need to improve its yield and broad adaptability in these harsh environments. In West Africa, for example, while sorghum production has doubled in the last 20 years, its yield has remained stagnant – and low.

The GCP Sorghum Research Initiative comprises several projects, which are exploring ways to use molecular-breeding techniques to improve sorghum yields, particularly in drylands. All projects are interdisciplinary international collaborations with an original focus on Mali, where sorghum-growing areas are large and rainfall is getting more erratic and variable. Through the stay-green project, the research has since broadened to also cover Burkina Faso, Ethiopia, Kenya, Niger and Sudan.

Using molecular markers is new and exciting for us as it will speed up the breeding process. With molecular markers, you can easily see if the plant you’ve bred has the desired characteristics without having to grow the plant and or risk missing the trait through visual inspection.”

What’s MARS got to do with it?

Niaba Témé is a local plant breeder and researcher at Mali’s L’Institut d’économie rurale (IER). He grew up in a farming community on the southern edge of the Sahara Desert, where crops would constantly fail during drier-than-normal seasons.

Niaba says these crop failures were in part his inspiration for a career where he could help farmers like his parents and siblings protect themselves from the risks of drought and extreme temperatures.

For the past four years, Niaba and his team at IER have been collaborating with Jean-François Rami and his team at France’s Centre de coopération internationale en recherche agronomique pour le développement (CIRAD), to improve sorghum grain yield and quality for West African farmers. The work is funded by the Syngenta Foundation for Sustainable Agriculture.

“With the help of CIRAD and Syngenta, we have been learning how to use molecular markers to improve breeding efficiency of sorghum varieties more adapted to the variable environment of Mali and surrounding areas which receive less than 600 millimetres of rainfall per year,” he says.

Jean-François Rami

“Using molecular markers is new and exciting for us as it will speed up the breeding process. With molecular markers, you can easily see if the plant you’ve bred has the desired characteristics without having to grow the plant and or risk missing the trait through visual inspection.”

Jean-François Rami, who is the project’s Principal Investigator, has been impressed by the progress made so far. Jean-François is also GCP’s Product Delivery Coordinator for sorghum.

“Since its inception, the project has progressed very well,” says Jean-François. “With the help of the IER team, we’ve been able to develop two bi-parental populations from elite local varieties, targeting two different environments of sorghum cropping areas in Mali. We’ve then been able to use molecular markers through a process called marker-assisted recurrent selection [MARS] to identify and monitor key regions of the genome in consecutive breeding generations.”

The collaboration with Syngenta came from a common perspective and understanding of what approach could be effectively deployed to rapidly deliver varieties with the desired characteristics.

“Syngenta came with their long experience in implementing MARS in maize. They advised on how to execute the programme and avoid critical pitfalls. They offered to us the software they have developed for the analysis of data which allowed the project team to start the programme immediately,” says Jean-François.

Like all GCP projects, capacity building is a large part of the MARS project. Jean-François says GCP has invested a lot to strengthen IER’s infrastructure and train field technicians, researchers and young scientists. But GCP is not the only player in this: “CIRAD has had a long collaboration in sorghum research in Mali and training young scientists has always been part of our mission. We’ve hosted several IER students here in France and we are interacting with our colleagues in Mali either over the phone or travelling to Mali to give technical workshops in molecular breeding. The Integrated Breeding Platform [IBP] has also been a breakthrough for the project, providing to the project team breeding services, data management tools, and a training programme – the Integrated Breeding Multiyear Course [IB–MYC].”

We don’t have these types of molecular-breeding resources available in Mali, so it’s really exciting to be a part of this project… the approach has the potential to halve the time it takes to develop local sorghum varieties with improved yield and adaptability to drought… one of the great successes of the project has been to bring together sorghum research groups in Mali in a common effort to develop new genetic resources for sorghum breeding.”

Back-to-back: more for Mali’s national breeding programme

On the back of the MARS project, Niaba successfully obtained GCP funding in 2010 to carry out similar research with CIRAD and collaborators in Africa at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).

“In this project, we are trying to enhance sorghum grain yield and quality for the Sudano-Sahelian zone of West Africa using the backcross nested association mapping (BCNAM) approach,” explains Niaba, who is the Principal Investigator of the BCNAM project. “This involves using an elite recurrent parent that is already adapted to local drought conditions. The benefit of this approach is that it can lead to detecting elite varieties much faster.”

Eva Weltzien has been the Principal Scientist for ICRISAT’s sorghum breeding programme in Mali since 1998. She says the project aligned with much of the work her team had been doing, so it made sense to collaborate considering the new range of sorghum genetic diversity that this approach aims to use.

“We’ve been working with Niaba’s team to develop 100 lines for 50 populations from backcrosses carried out with 30 recurrent parents,” explains Eva. “These lines are being genotyped by CIRAD. We will then be able to use molecular markers to determine if any of these lines have the traits we want. We don’t have these types of molecular-breeding resources available in Mali, so it’s really exciting to be a part of this project.”

Also on display are panicles and seed of the hybrids and released varieties of sorghum in Mali.

Eva says that the approach has the potential to halve the time it takes to develop local sorghum varieties with improved yield and adaptability to drought.

For Jean-François, one of the great successes of the project has been to bring together sorghum research groups in Mali in a common effort to develop new genetic resources for sorghum breeding.

“This project has strengthened the IER and ICRISAT partnerships around a common resource. The large multiparent population that has been developed is analysed collectively to decipher the genetic control of important traits for sorghum breeding in Mali,” says Jean-François.

Plants with this ‘stay-green’ trait keep their leaves and stems green during the grain-filling period. Typically, these plants have stronger stems, higher grain yield and larger grain.”

Sorghum staying green and strong, with less water

In February 2012, Niaba and his colleague, Sidi B Coulibaly, were invited to Australia as part of another Sorghum Research Initiative project they had been collaborating on with CIRAD, Australia’s University of Queensland and the Queensland Department of Agriculture, Fisheries and Forestry (QDAFF).

“We were invited to Australia for training by Andrew Borrell and David Jordan, who are co-Principal Investigators of the GCP stay-green sorghum project,” says Niaba.

Left to right: Niaba Témé (Mali), David Jordan (Australia), Sidi Coulibaly (Mali) and Andrew Borrell (Australia) visiting an experiment at Hermitage Research Facility in Queensland, Australia.

“We learnt about association mapping, population genetics and diversity, molecular breeding, crop modelling using climate forecasts, and sorghum physiology, plus a lot more. It was intense but rewarding – more so the fact that we understood the mechanics of these new stay-green crops we were evaluating back in Mali.”

It wasn’t all work and there was clearly also time to play, as we can see here., where Sidi Coulibaly and Niaba Témé are visiting the Borrell family in Queensland, Australia.

Stay-green is a post-flowering drought adaptation trait that has contributed significantly to sorghum yield stability in northeastern Australia and southern USA over the last two decades.

Andrew has been researching how the drought-resistant trait functions for almost 20 years, including gene discovery. In 2010, he and his colleague, David Jordan, successfully obtained funding from GCP to collaborate with IER and CIRAD to develop and evaluate drought-adapted stay-green sorghum germplasm for Africa and Australia.

“Stay-green sorghum grows a canopy that is about 10 per cent smaller than other lines. So it uses less water before flowering,” explains Andrew. “More water is then available during the grain-filling period. Plants with this ‘stay-green’ trait keep their leaves and stems green during the grain-filling period. Typically, these plants have stronger stems, higher grain yield and larger grain.”

Andrew says the project is not about introducing stay-green into African germplasm, but rather, enriching the pre-breeding material in Mali for this drought-adaptive trait.

The project has three objectives:

To evaluate the stay-green drought-resistance mechanism in plant architecture and genetic backgrounds appropriate to Mali.

To develop sorghum germplasm populations enriched for stay-green genes that also carry genes for adaptation to cropping environments in Mali.

To improve the capacity of Malian researchers by carrying out training activities for African sorghum researchers in drought physiology and selection for drought adaptation in sorghum.

…we have found that the stay-green trait can improve yields by up to 30 percent in drought conditions with very little downside during a good year, so we are hoping that these new lines will display similar characteristics”

Expansion and extension: beyond Mali to the world

Andrew explains that there are two phases to the stay-green project. The project team first focused on Mali. During this phase, the Australian team enriched Malian germplasm with stay-green, developing introgression lines, recombinant inbred lines and hybrids. Some of this material was field-tested by Sidi and his team in Mali.

“In the past, we have found that the stay-green trait can improve yields by up to 30 percent in drought conditions with very little downside during a good year, so we are hoping that these new lines will display similar characteristics,” says Andrew. “During the second phase we are also collaborating with ICRISAT in India and now expanding to five other African countries – Niger and Burkina Faso in West Africa; and Kenya, Sudan and Ethiopia in East Africa. During 2013, we grew our stay-green enriched germplasm at two sites in all these countries. We also hosted scientists from Burkina Faso, Sudan and Kenya to undertake training in Queensland in February 2014.”

(3) Clement Kamau (left, Kenya Agricultural Research Institute [KARI] ) and Andrew Borrell (right) visiting the seed store at KARI, Katumani, Kenya.

Andrew says that the collaboration with international researchers has given them a better understanding of how stay-green works in different genetic backgrounds and in different environments, and the applicability is broad. Using these trial data will help provide farmers with better information on growing sorghum, not just in Africa and Australia, but also all over the world.

“Both David and I consider it a privilege to work in this area with these international institutes. We love our science and we are really passionate to make a difference in the world with the science we are doing. GCP gives us the opportunity to expand on what we do in Australia and to have much more of a global impact.”

We’ll likely be hearing more from Andrew on the future of this work at GCP’s General Research Meeting (GRM) in October this year, so watch this space! Meantime, see slides below from GRM 2013 by the Sorghum Research Initiative team. We also invite you to visit the links below the slides for more information.

Triumphs and tragedies, pitfalls and potential of the ‘camel crop’

We travel through space and time, with a pair of researchers who have a pronounced passion for a plant brought to Africa by seafaring Portuguese traders in the 16th century. Fastforwarding to today, half a millennium later, the plant is widespread and deep inland, and is the staple food for Africa’s most populous nation – Nigeria.

Meet cassava, the survivor. After rice and maize, cassava is the third-largest source of carbohydrate in the tropics. Surviving, nay thriving, in poor soils and shaking off the vagaries of weather – including an exceptionally high threshold for drought – little wonder that cassava, the ‘camel’ of crops is naturally the main staple in Nigeria. And with that, it has propelled Nigeria to the very top of the cassava totem pole as the world’s leading cassava producer, and consumer: most Nigerians eat cassava in one form or another practically every day.

Great, huh? But there’s also a darker side to cassava, as we will soon find out from our two cassava experts. For starters, the undisputed global cassava giant, Nigeria, produces just enough to feed herself. Even if there were a surplus for the external demand, farming families, which make up 70 percent of the Nigerian population, have limited access to these lucrative external markets. Secondly, cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are deadly in Africa. Plus, cassava is a late bloomer (up to two years growth cycle, typically one year), so breeding and testing improved varieties takes time. Finally, cassava is most definitely not à la mode at all in modern crop breeding: the crop is an unfashionably late entrant into the world of molecular breeding, owing to its complex genetics which denied cassava the molecular tools that open the door to this glamour world of ‘crop supermodels’.

But all is not doom and gloom, which inexorably dissolve in the face of dogged determination. All the above notwithstanding, cassava’s green revolution seems to be decidedly on the way in Nigeria, ably led by born-and-bred sons of the soil: Chiedozie Egesi and Emmanuel Okogbenin (pictured right) are plant breeders and geneticists at the National Root Crops Research Institute (NRCRI). With 36 years’ collective cassava research experience between them, the two men are passionate about getting the best out of Nigeria’s main staple crop, and getting their hands into the sod while about it: “I’m a plant breeder,” says Chiedozie, with pride. “I don’t just work in a laboratory. I am also in the field to experience the realities.”

Hitting two birds with one stone…two stones are even better!As Principal Investigators (PIs) leading three different projects in the GCP-funded Cassava Research Initiative, Chiedozie and Emmanuel, together with other colleagues from across Africa, form a formidable team. They also share a vision to enable farmers increase cassava production for cash, beyond subsistence. This means ensuring farmers have new varieties of cassava that guarantee high starch-rich yields in the face of evolving diseases and capricious weather.

Chiedozie is one of cassava’s biggest fans. His affection for, and connection to, cassava is almost personal and definitely paternal. He is determined to deploy the best plant-breeding techniques to not only enhance cassava’s commercial value, but to also protect the crop against future disease outbreaks, including ‘defensive‘ breading. But more on that later…

Emmanuel is equally committed to the cassava cause. As part of his brief, Emmanuel liaises with the Nigerian government, to develop for – and promote to – farmers high-starch cassava varieties. This ensures a carefully crafted multi-pronged strategy to revolutionise cassava: NRCRI develops and releases improved varieties, buttressed by financial incentives and marketing opportunities that encourage farmers to grow and sell more cassava, which spurs production, thereby simultaneously boosting food security while also improving livelihoods.

Standing tall. Disease resistance and high starch and yield aside, farmers also prefer an upright architecture, which not only significantly increases the number of plants per unit, but also favours intercropping, a perennial favourite for cassava farmers.

Cross-continental crosses and cousins, magic for making time, and clocking a first for cassava

No one has been able to manufacture time yet, so how can breeders get around cassava’s notoriously long breeding cycle? MAS (marker-assisted selection) is crop breeding’s magic key for making time. And just as humans can benefit from healthy donor organ replacement, so too does cassava, with cross-continental cousins donating genes to rescue the cousin in need. Latin American cassava is nutrient-rich, while African cassava is hardier, being more resilient to pests, disease and harsh environments.

Thanks to marker-assisted breeding, CMD resistance from African cassava can now be rapidly ‘injected’ much faster into Latin American cassava for release in Africa. Consequently, in just a three-year span (2010–2012), Chiedozie, Emmanuel, Martin Fregene of the Donald Danforth Plant Science Center (USA) and the NRCRI team, released two new cassava varieties from Latin American genetic backgrounds (CR41-10 and CR36-5). These varieties, developed with GCP funding, are the first molecular-bred cassava ever to be released, meaning they are a momentous milestone in cassava’s belated but steady march towards its own green revolution.

Marker-assisted selection is much cheaper, and more focused.”

On the cusp of a collaborative cassava revolution: on your marks…With GCP funding, Chiedozie and Emmanuel have been able to use the latest molecular-breeding techniques to speed up CMD resistance. Using marker-assisted selection (MAS) which is much more efficient, the scientists identified plants combining CMD resistance with desirable genetic traits.

“MAS for CMD resistance from Latin American germplasm is much cheaper, and more focused,” explains Emmanuel. “There is no longer any need to ship in tonnes of plant material to Africa. We can narrow down our search at an early stage by selecting only material that displays markers for the genetic traits we’re looking for.” Using markers, combining traits (known as ‘gene pyramiding’) for CMD resistance is faster and more efficient, as it is difficult to distinguish phenotypes with multiple resistance in the field by just observing with the naked eye. This is what makes marker-assisted breeding so effective and desirable in Africa.

GCP’s mode of doing business coupled with its community spirit has spurred the NRCRI scientists to cast their eyes further out to the wider horizon beyond their own borders.

By collaborating with research centres in other parts of the world, Emmanuel and Chiedozie have made remarkable strides in cassava breeding. According to Emmanuel, “GCP helped us make links with advanced laboratories and service providers like LGC Genomics. The outsourcing of genotyping activities for molecular breeding initiatives is very significant, as it enables us to carry out analyses not otherwise possible.”

We can’t afford to sit idle until it comes – we need to be armed and on the ready.”

‘Defensive’ breeding: partnerships to pre-empt catastrophe and combat disease
Closer home in Africa, as PI of the corollary African breeders community of practice (CoP) project, Emmanuel co-organises regular workshops with plant breeders from a dozen other countries (Côte d’Ivoire, DR Congo, Ethiopia, Ghana, Kenya, Liberia, Malawi, Mozambique, Sierra Leone, Tanzania, Uganda and South Sudan). These events are an opportunity to share knowledge on molecular breeding and compare notes.

Of the diseases that afflict cassava, CBSD is the most devastating. Mercifully, in Nigeria, the disease is non-existent, but Chiedozie is emphatic that this is by no means cause for complacency. “If CBSD gets to Nigeria, it would be a monumental catastrophe!” he cautions. “We can’t afford to sit idle until it comes – we need to be armed and on the ready.”

Putting words to action, though this work on CBSD resistance is still in its early stages, more than 1,000 cassava genotypes (different genetic combinations) have already have been screened in the course of just one year. Chiedozie hopes that the team will be able to identify key genetic markers, and validate these in field trials in Tanzania, where CBSD is widespread. This East African stopover, Chiedozie emphasises, is a crucial checkpoint in the West African process. So the cassava CoP not only provides moral but also material support.

And Africa is not the limit. GCP-funded work on CMD resistance is more advanced than the CBSD work, though the real breakthrough in CMD only happened recently, on the international arena within which the African breeders now operate. According to Chiedozie, two entire decades of screening cassava genotypes from Latin America yielded no resistance to CMD. The reason for this is that although it is widespread in Africa, CMD is non-existent in Latin America.

Through international collaborative efforts, cassava scientists, led by Martin Fregene (now based in USA), screened plants from Nigeria and discovered markers for the CMD2 gene, indicating resistance to CMD. Once they had found these markers, the scientists were off and away! By taking the best of the Latin American material and crossing it with Nigerian genotypes that have CMD resistance, promising lines were developed from which the Nigerian team produced two new varieties. These varieties, CR41-10 and CR36-5, have already been released to farmers, and that is not all. More varieties bred using these two as parents are in the pipeline.

“GCP funding has given us the opportunity to show that a national organisation can do the job and deliver.”

Delivery attractsThe success of the CGP-funded cassava research in Nigeria lies in its in-country leadership. Chiedozie, Emmanuel and Martin are native Nigerian scientists and as such are – in many ways – best placed to drive a research collaboration to benefit the country’s farmers and boost food security. “GCP funding has given us the opportunity to show that a national organisation can do the job and deliver,” says Chiedozie.

This proven expertise has helped NRCRI forge other partnerships and attract more financial support, for example from the Bill & Melinda Gates Foundation for a project on genomic selection. GCP support has also bolstered communications with the Nigerian government, which has launched financial instruments, such as a wheat tariff,* to boost cassava production and use.

[Editors note: * wheat tariff: The Nigerian government is trying to reduce wheat import bills and also boost cassava commercialisation by promoting 20 percent wheat substitution in bread-making. Tariffs are being imposed on wheat to dissuade heavy imports and encourage utilisation of high-quality cassava flour for bread.]

“The government feels that to quickly change the fortunes of farmers, cassava is the way to go,” explains Emmanuel. He clarifies, “The tariff from wheat is expected to be ploughed back to support agricultural development – especially the cassava sector – as the government seeks to increase cassava production to support flour mills. Cassava offers a huge opportunity to transform the agricultural economy and stimulate rural development, including rapid creation of employment for youth.”

The Nigerian government is right in step aiding cassava’s march towards the crop’s own green revolution, as is evident in the the Minister of Agriculture’s tweet earlier this year, and in his video interview below. See also related media story, ‘Long wait for cassava bread’.

Clearly, the ‘camel’ crop – once considered an ‘orphan’ in research – has travelled as far in science as in geography, and it is a precious asset to deploy for food production in a climate-change-prone world. As Emmanuel observes, cassava’s future can only be brighter!

Two in one, in more ways than one

Armin Bhuiya

Armin Bhuiya (pictured) is a dynamic and lively young geneticist and plant breeder, who has made huge strides in tracking crucial genes in Bangladeshi rice landraces (or traditional farmer varieties). Armin took a ‘sandwich’ approach twinning two traits – salt and submergence tolerance – in order to boost farmers’ yields. Her quest for salt-impervious ‘amphibian’ rice has seen her cross frontiers to The Philippines, and back to her native Bangladesh with solutions that will make a difference, borrowing a leaf along the way from the mythical submarine world of Atlantis for life under water. Using cutting-edge crop science, Armin is literally recreating out-of-this-world stuff working two elements of the ancient world – earth and water – plus that commodity that was then so prized enjoying a premium comparable to gems: salt. Read on!

A rice heritage, and the ‘sandwich’ saga and submarine search both begin…

“My father worked at the Bangladesh Rice Research Institute (BRRI), which basically means I grew up in rice research. You could say that I was born and bred in agriculture and this inspired me to study agriculture myself,” says Armin. As a result of these early experiences, Armin started a master’s degree in 2006 on genetics and plant breeding, specialising in hybrid rice. Ever since, rice has been her religion, following in the footsteps of her father to join the Bangladesh Rice Research Institute (BRRI).

Her other defining hallmark is her two-in-one approach. Sample this: once she completed her two-in-one master’s, Armin went on to study for a PhD in the same twin areas at Bangladesh Agricultural University. Pondering long and hard on what research would be of most practical use, she asked herself “What is the need? What research will be useful for my country and for the world?” (Editorial aside: out of this world work, apparently…)

Not content pondering over the question by herself, her natural two-track approach kicked in. Mulling with her colleagues from BRRI, the answer, it first seemed, was to find ways to produce salt-tolerant high-yielding rice. In Bangladesh and many other parts of South and Southeast Asia, climate change is driving up the sea level, spreading salinity further and deeper across low-lying coastal rice-fields, beyond the bounds where salt-drenched terrain has long been a perennial problem. Modern rice varieties are highly sensitive to salt. So, despite the low yields and quality, farmers continue to favour hardy traditional rice landraces that can take the heat and hit from the salt. Proceeding from this earthy farmer reality and inverting the research–development continuum, Armin needed no further thinking as the farmers showed the way to go. Her role and the difference she could make was to track the ‘treasure’ genes locked in these landraces that were transferred to high-yielding but salt-sensitive rice varieties, to fortify them against salt.

But that was not all. There’s power in numbers and consulting others, harnessing the best in diversity. In comes the two-track approach again, with Armin now turning to fellow scientists again, with the reality from farmers. Upon further consultations with colleagues, yet another fundamental facet emerged that could not be ignored. Apparently, salt-impervious rice alone would not be not enough, and here’s why. Salt and tides aside, during the rainy season inland, flash floods regularly submerge the fields, literally drowning the crop. More than 20 million hectares in South and Southeast Asia are affected – including two million hectares in coastal Bangladesh alone. The southern belt of Bangladesh is particularly affected, as modern varieties are sensitive to not only submergence but also salinity. So Armin had her work cut out for her, and she now knew that for the fruit of her labour to boost rice production in coastal regions as well (two tracks again! Inland and coastal low-lying rice-lands), what she needed to do was to work on producing high-yielding, salt-impervious, ‘amphibian’ rice that could withstand not only salinity but also submarine life. In other words, pretty much rice for a latter-day real-life rendition of the mythical Atlantis.

Armin has successfully incorporated dual tolerance to salinity and submergence in the popular Bangladeshi mega-variety BR11. This will provide the ideal salt-tolerant ‘amphibian’ rice suitable for farmers in the flood-prone salty-water-drenched swaths of southern Bangladesh.”

Through the door of opportunityThe opportunity that opened the door for Armin to fulfil her dream was a DuPont Pioneer postgraduate fellowship implemented by GCP. The competitive programme provides grants for postgraduate study in plant breeding and genetics to boost the yields of staple food crops. This fellowship took Armin to Filipino shores and the molecular breeding labs at the International Rice Research Institute (IRRI). Here she got what she terms a golden opportunity to work under the tutelage of Abdelbagi Ismail, a leading plant physiologist focusing on overcoming abiotic stresses. From him, Armin learnt how carry out the precise meticulous research required for identifying quantitative trait loci (QTLs).

Armin at work at the IRRI greenhouse in 2011.

Armin conducted her research with two different mapping populations, both derived from Bangladeshi landraces (Kutipatnai and Ashfal). She found a total of nine quantitative trait loci (QTLs) from one mapping population and 82 QTLs from another for tolerance to salinity stress at seedling stage (QTL is a gene locus where allelic variation is associated with variation in a quantitative trait). Incorporating these additional genes into a high-yielding variety will help to develop promising salt-tolerant varieties in future. She has also successfully incorporated QTLs for dual tolerance to salinity (Saltol) and submergence (Sub1) in the popular Bangladeshi mega-variety, BR11. Stacking (or ‘pyramiding’ in technical terms) Saltol and Sub1 QTLs in BR11 will provide the ideal salt-tolerant ‘amphibian’ rice suitable for farmers in the flood-prone salty-water-drenched swaths of southern Bangladesh.

I know what to do and what is needed… I am going to share what I learned with my colleagues at BRRI and agricultural universities, as well as teach these techniques to students”

Dream achiever and sharer: aspiring leader inspiring changeThe Pioneer–GCP fellowship has given Armin the opportunity to progress professionally. But, more than that, it means that through this remarkable young scientist, others from BRRI will benefit – as will her country and region. “While I was at IRRI,” Armin says, “I trained myself in modern molecular plant-breeding methods, as I knew that this practical experience in high-tech research methods would definitely help Bangladesh. I know what to do and what is needed. I am going to share what I learned with my colleagues at BRRI and agricultural universities, as well as teach these techniques to students. It makes me very happy and my parents very proud that the fellowship has helped me to make my dream come true.”

Away from professional life, there have been benefits at home too, with these benefits delivered with Armin’s aplomb and signature style in science – doing two in one, in more ways than one. This time around, the approach has led to dual doctorates for a dual-career couple in different disciplines: “When I went to The Philippines” Armin reveals, “my husband decided to come with me, and took the opportunity to study for a PhD in development communications. So we were both doing research at the same time!”

While Armin’s research promises to make a real difference in coastal rice-growing areas, Armin herself has the potential to lead modern plant breeding at her institute, carry GCP work forward in the long term, post-GCP, and to inspire others as she herself was inspired – to make dreams come true and stimulate change. An inspired rice scientist is herself an inspiration. You will agree with us that Armin personifies Inspiring change, our favoured sub-theme for International Women’s Day this year.

Go, Armin, Go! We’re mighty proud of what you’ve achieved, which we have no doubt serves as inspiration for others!

Drought stalks, some dieDespite the widespread cultivation of beans in Africa, yields are low, stagnating at between 20 and 30 percent of their potential. Drought brought about by climate change is the main culprit, afflicting 70 percent of Africa’s major bean-producing regions in Southern and Eastern Africa.

Today we turn the spotlight on Zimbabwe, where drought is a serious and recurrent problem. Crop failure is common at altitudes below 800 meters, and livestock death from shortage of fodder and water are all too common. In recent history, nearly every year is a drought year in these low-lying regions frequently plagued by delayed rains, as well as by intermittent and terminal drought.

The ‘battleground’ and ‘blend’Zimbabwe is divided into five Natural Regions or agroecological zones. More than 70 percent of smallholder farmers live in Natural Region 3, 4 and 5, which jointly account for 65 percent of Zimbabwe’s total land area (293,000 km2). It is also here that the searing dual forces of drought and heat combine to ‘sizzle’ and whittle bean production.

The rains are insufficient for staple foods such as maize, and some of their complementary legumes such as groundnuts. In some areas where temperatures do not soar too high (less than 30oC), beans blend perfectly into the reduced rainfall regime that reigns during the growing season.

A deeper dig: the root of the matter

Godwill Makunde

Research from Phase I of the Tropical Legumes I (TLI) project under GCP’s Legume Research Initiative showed that deep rooting is one of the ways to confer drought tolerance in common beans. High plant biomass at pod-filling stage also confers drought tolerance. “These important findings from TLI refined our breeding objectives, as we now focus on developing varieties combining deep roots and high plant biomass,” reveals Godwill Makunde (pictured), a bean breeder at Zimbabwe’s Crop Breeding Institute (CBI), which falls under the under the country’s Department of Research & Specialist Services. Zimbabwe is one the four target countries in Eastern and Southern Africa for GCP’s bean research (the other three being Ethiopia, Kenya and Malawi).

From America to Africa…the heat is on, so is the battle…

The battle is on to beat the heat: through the project, CBI received 202 Mesoamerican and Andean bean breeding lines from the reference set collection held by the International Center for Tropical Agriculture (CIAT, by its Spanish acronym). A ‘reference set’ is a sub-sample of existing germplasm collections that facilitates and enables access to existing crop diversity for desired traits, such as drought tolerance or resistance to disease or pests. The Institute also embarked on bringing in more techniques to breed for heat tolerance.

Kennedy Simango

Drought, pests and disease“We embraced mutation breeding in collaboration with the International Atomic Energy Agency, and we primarily look for heat tolerance in small-seeded beans,” says Kennedy Simango (pictured right and below), a plant breeder at CBI. “Preliminary results suggested that just like drought, the reproductive stages of common bean are when the crop is most sensitive to heat. Flower- and pod-drop are common. Yield components and yields are severely reduced. In addition, we also focus on developing pest- and disease-resistant varieties.”

Kennedy Simango at work a the Crop Breeding Institute.

The CBI project’s primary diseases and pests of focus are angular leaf spot (ALS), common bacterial blight (CBB), rust and bean stem maggot, and aphids. “This came from our realisation that drought co-exists with heat, diseases and pests,” Kennedy adds. “So, a variety combining drought, heat, disease and pest tolerance all together would increase common bean productivity under harsh environments or drought-prone areas.”

At first glance, piling up all these vital survival traits may appear insurmountable, but it is all feasible, thanks to advances in plant science. “Breeding methods are changing rapidly, and it is vital that we keep up with the technology,” says Kennedy.

The CBI team is using molecular breeding to identify drought-tolerant parents, and then cross them into preferred bean varieties to confer to the ‘offspring’ the best of both worlds – drought tolerance and market appeal.

All-round capacity and competenceGCP’s support does not stop at enabling access to breeding lines alone, or introduction to molecular breeding. “We got a lyophiliser, which is specialised equipment that enables us to extract DNA and send it for genotyping,” says Kennedy. “From the genotyping exercise, we hope to be able to trace the relationships among breeding lines so that we design better crossing programmes, and thereby maximise the diversity of our breeding lines. In addition, we hope to select recombinants carrying desirable genes in a short period of time, and at times without even needing to test them in the target environment.” GCP assists with genotyping through its Genotyping Support Service offered through the Integrated Breeding Platform.

Human resources have not been forgotten either. Godwill Makunde, a CBI bean breeder, is studying for a TLII-funded PhD in Plant Breeding at the University of the Free State, South Africa. A group of four scientists (Godwill and Kenedy, plus Charles Mutimaamba, and Munyaradzi Mativavarira) are in GCP’s three-year Integrated Breeding Multi-Year Course (IB–MYC). The curriculum includes design of experiments, data collection, analysis and interpretation, molecular breeding and data management techniques. In addition, GCP also trains research technicians. For CBI, Clever Zvarova, Anthony Kaseke, Mudzamiri and Chikambure have attended this training. Their course also includes phenotyping protocols (data collection and use of electronic tablets in designing field-books). To date, CBI has received five tablets for digital data collection , of which two are outstanding.

Godwill doing what he does best: bean breeding.

Bringing it all together, and on to farmsBut how relevant are all these breeder-focused R&D efforts to the farmer? Let’s review this in proper context: in the words of Mr Denis Mwashita, a small-scale farmer at the Chinyika Resettlement Scheme in Bingaguru, Zimbabwe, “Beans have always carried disease, but from the little we harvest and eat, we and our children have developed stomachs.”

“What Mr Mwashita means is that despite the meagre harvests, farm families fare better in terms of health and nutrition for having grown beans,” explains Godwill.

With this solid all-round support in science, working partnerships, skills and infrastructure, the CBI bean team is well-geared to breed beans that beat both heat and disease, thereby boosting yields, while also meeting farmer and market needs. Trials are currently underway to select lines that match these critical needs which are the clincher for food security.

“The Zimbabwe market is used to the sugar type, which is however susceptible to drought. We hope to popularise other more drought-tolerant types,” says Kennedy. “We plan to selected a few lines in the coming season and test them with farmers prior to their release. Our goal is to have at the very least one variety released to farmers by mid-2013.”

A noble goal indeed, and we wish our Zimbabwe bean team well in their efforts to improve local food security.

I was forever inquisitive as to how things grew, and questioning when they didn’t grow well. I think it’s what got me interested in plant science.”
– Abdelbagi Ismail, Plant Physiologist and Principal Scientist, International Rice Research Institute.

Today, we talk to Abdel. His riveting voyage in plant science starts on the bountiful banks of the Nile, before we sail on to Asia’s ricelands. We’ll make a short stopover in USA for cowpeas and drought in between, then proceed to to our main meal of rice, spiced and seasoned with a strong dash of salt-and-P.

It’s not just about food, but also family: you’ll get to meet a sister Challenge Programme along the way. Intrigued? We hope so, so please do read on!

‘A’ for Abdel and agriculture – an early passion for plantsFrom a tender age, Abdel was fascinated by agriculture.

Growing up on a small family farm backing onto the banks of the Nile in the Northern State of Sudan, he helped his parents in tilling the land, sowing and harvesting.

Abdel reminisces, “It was a relaxing paradise with all types of fruit growing around you year-round. Working and living on a farm, I was forever inquisitive as to how things grew, and questioning when they didn’t grow well. I think it’s what got me interested in plant science.”

Armed with a Bachelor’s and Master’s in Agricultural Sciences (agronomy, crop production, water relations) from the University of Khartoum, Sudan, Abdel moved to the University of California, Riverside, USA, for a PhD on drought tolerance in cowpeas.

“It was the first time I had ever left Africa, and it was a real eye-opener,” Abdel recalls. “It was a fantastic new page in my career too, as I was working with world-class professors and mentors. I chose to work on cowpeas because it is a hardy crop that can be grown in dry conditions which were – and still are – becoming more prevalent in sub-Saharan Africa.” (you can take a sidetrack here, to see our research on cowpeas)

What interests me is how some societies have survived, and, in some cases, flourished because they invested in improving their plants and crops to adapt and adjust to weather adversities.”

Navigating away from the Nile, and discovering his nicheFor this native son of the Nile, this move was a watershed. It marked the start of a dedicated – and still ongoing – career quest to understand how plants can adapt to better tolerate extreme environmental stresses such as higher and lower temperatures, too much or too little water, salinity, and nutrient imbalances.

“Abiotic stresses have had, and continue to have, a major impact on human life, with some societies disappearing altogether because of changes in soils or climate,” says Abdel. “What interests me is how some societies have survived, and, in some cases, flourished because they invested in improving their plants and crops to adapt and adjust to weather adversities.”

From time immemorial, the communities around the Nile where Abdel spent his childhood are a prime example of this flourishing against adversity.

IRRI beckons, and nurturesIn 2000, Abdel accepted a position at the International Rice Research Institute (IRRI) in The Philippines.

“I saw it as an opportunity to convert knowledge and scientific discoveries into resources that could help needy farmers,” explains Abdel.

Abdel confesses that when he joined IRRI, his intention was to stay for a short stint and then move on. But as he became more involved in his work, he felt IRRI offered him the best opportunity to build his career, and to contribute to global food-security issues.

“I’ve been here for 12 years now. IRRI really is a great place to grow as a person and a researcher, and to learn how to become a leader.”

Having GCP provide ongoing funding and support for public institutions to conduct a long-term project has been pivotal to the success of the project. It has given us all the security we need to focus on conducting the complex research required…”

Trailblazing for GCP : a much-needed dash of ‘salt-and-P’In 2004, Abdel proposed a collaborative project between nine different research organisations, across seven countries, to improve salt tolerance and phosphorus uptake efficiency in rice. The work was funded by a sister CGIAR Challenge Programme on Water and Food (CPWF).

This work caught – and held – GCP’s attention, because it sought to overcome a problem that negatively affects the lives of tens of thousands of rice growers around the world. The two resultant GCP-funded IRRI-led projects involved partners from Bangladesh, India, Indonesia, Vietnam and USA’s University of California, Davis. Globally, more than 15 million hectares of ricelands are saline, and more than one-third of all ricelands are phosphorus-deficient, hitting poor communities hardest.

In the nine years since, and together with his colleagues and partners, Abdel has developed the proposal into a productive and coherent suite of interconnected projects: he has managed and overseen most of the progress made during the discovery of the genes associated with salinity tolerance (Saltol) and phosphorus uptake (Pup1), and their insertion into well-known rice varieties that farmers in Bangladesh, Indonesia and The Philippines know and trust.

It’s all about rice: salt tolerance (Saltol) ‘meets’ phosphorus uptake (Pup1) in Bangladesh. Abdel is on the extreme right. Next to him is Sigrid Heuer, Principal Investigator of the ‘Pup1’ work.

Keeping the faith, and going where no rice has gone before…A long-term horizon helps, since, just like art, science cannot be hurried: “Having GCP provide ongoing funding and support for public institutions to conduct a long-term project has been pivotal to the success of the project,” Abdel emphasises.

“It has given us all the security we need to focus on conducting the complex research required to advance our knowledge about these genes, then breed and develop popular varieties containing then. In some cases, we have developed lines with doubled yields, and grown rice in areas where it has never been grown before because the land was too saline.”

For Abdel, such achievements are heartening as they provide farmers with greater food and income security, which in turn improves their and their community’s livelihoods.

“It brings a smile to my face whenever I think about how our work helps to produce higher-yielding crops for poverty-stricken countries whose farmers often can only afford to grow one crop per year,” says Abdel sincerely.

Abdel continues to build upon, and has even employed, partners he has met through the GCP project…”We want to improve their capacity to take up new breeding techniques, such as the use of molecular markers, which can reduce the time it takes to breed new varieties from six to 10 years to two to three years…”

Continually building on the bestSo what’s in store for the future?

Having discovered the Saltol gene and developed experimental lines, his team is now training breeders from country breeding programmes on how they can successfully breed for salt tolerance and tolerance of other abiotic stresses using their own popular varieties, thereby fortifying popular varieties with these much-needed tolerance traits.

“We want to improve their capacity to take up new breeding techniques, such as the use of molecular markers, which can reduce the time it takes to breed new varieties from six to 10 years to two to three years,” reveals Abdel. “This will allow them to breed for crops quicker, in response to ever-changing and extreme climate conditions.”

As for his other projects with IRRI, Abdel continues to build upon, and has even employed, partners he has met through the GCP project to help him with his Stress tolerant rice for Africa and South Asia (STRASA) project.

GCP helped IRRI attract support from other funders…”

Going further, faster, together… five and counting, still learning, and the future looks brightSTRASA is almost five years old and has another five years left to run.

“GCP helped IRRI to attract additional support from other funders, such as the Bill & Melinda Gates Foundation, to start STRASA, which seeks to support the development and distribution of stress-tolerant varieties in Africa and South Asia,” Abdel explains.

Abdel’s parting words? “I’m still committed to understand how plants can be manipulated to adapt to, and better tolerate, extreme environmental stresses, which seems more feasible today than it has ever been before.”

The TLI project lets us know about molecular breeding, so it’s exposed us to new developments in science, especially in the application of molecular techniques and plant breeding.”– Asrat Asfaw Amele, Southern Agricultural Research Institute, Ethiopia

Many a tale about Ethiopia will regale the reader with details of its contrasting landscape, numerous rivers, searing regional temperatures, the multicultural makeup of its society, its world-famous, unbeatable long-distance and high-altitude runners, its rich history and culture; a sweet producer of honey, the home of coffee, and origin of all mankind…

Seeing red… but no blood
…I found a land of incurably hospitable and kind people, proud of their country and culture; infectiously good music, incredibly strong coffee, where they love both bloody raw meat and protein-rich red beans, dubbed ‘bloodless meat’ in this part of the world.

Cool early morning departure

Out & about
My first real taste of Ethiopia was out in the countryside where I visited the work of GCP’s Tropical Legumes I (TLI) project in the field, on a trip to the bean fields at the Southern Agricultural Research Institute’s (SARI) research stations at Areka and Hawassa, which took us on a 600-km round tour, out of the capital Addis Ababa and into the Great Rift Valley beyond.

We set off early that cool morning, and as we headed into the countryside, I glimpsed many a local taking their first breath of morning air as they stepped outside from their decoratively-painted, round, thatched-roof homes, and shook the night’s sleep from their shoulders.

Traditional thatched living rooms

So their day began – already there was smoke coming from the chimneys, and I imagined the lady of the house beginning to prepare for the first coffee ceremony of the day. Coffee is often accompanied by a dish of boiled red beans. Or maybe she was warming the pan for the morning injera – a kind of ‘teff tortilla’: a sour-dough thin pancake made of the local cereal, teff. Injera is an iconic ubiquitous component of Ethiopian cuisine, with which diners take all manner of wat, or stew made from a rich variety of ingredients – from legumes to raw meat, carefully rolling the spongy crepe around the filling twice, making sure no food falls onto the fingers, for dining etiquette strictly dictates against the licking of fingers.

Ensete plantations

Living landscape

We pass score upon score of the gently-smoking thatched round huts – the traditional ‘living rooms’ in these parts; most dwellings are accompanied by modest smallholdings, with maybe a grazing goat or two, and many more with plantations of ensete – a banana-like plant, which, in spite of its inedible fruit, has long been a staple in Ethiopia. It is used for its root, which is mashed to make a tasty, stodgy, bread-like food called kocho, used to accompany meals, a denser cousin of the favourite injera. These smallholdings would also be the perfect size for cultivating beans, as they are not an acre-hungry crop, but grow happily on small plots of land, and in some areas are intercropped with ensete to maximise the space.

Dromedaries, drought and beans

Our common legume: the bean, Phaseolus vulgaris L

Into this landscape we pass the incongruous addition of a herd or two of camels with their owners…significantly peculiar as these aren’t desert lands, but the edge of the Ethiopian highlands, gradually and graciously giving way to the majestic Great Rift Valley below. I ask my guide about the addition of camel hands to this highland scenery: he explains their strange presence is due to a growing food shortage which has forced these nomadic peoples further afield to find their fare. The appearance of these dromedaries and their human partners brings harshly to mind Ethiopia’s most notorious claim to fame – especially for anyone who recalls the mid-1980s – for whom Ethiopia will always be indelibly synonymous with famine. It also throws the work of GCP, and specifically TLI, sharply into the spotlight, for the over-arching objective of this project is to improve legume productivity in environments considered marginal for agriculture, due to heat and other stresses. Somehow, it seems that more of the world’s environment is becoming ‘stressed’ by the day, though luckily the giant beanstalk of our story is a hardy crop which can be grown on the poor soils and fragmented plots of these challenged lands.

So the legume of choice for this most uncommon road trip is the common bean, Phaseolus vulgaris L, and our Ethiopian bean breeding expert is Asrat Asfaw Amele of the Southern Agricultural Research Institute (SARI), who is the Lead Scientist of the TLI beans component in Ethiopia. Asrat is our friendly guide and fount of knowledge of all things Ethiopian throughout this impassioned passage into the ‘bean valley’, and we are accompanied by Bodo Raatz of the Centro Internacional de Agricultura Tropical (CIAT), recently appointed Principal Investigator of TLI’s bean research. At Areka research station we are joined on our journey by Daniel A Demissie, who, along the way, shares his many insights on beans, diseases such as bean stem maggot (BSM), and on drought . We are chaperoned throughout by our courageous driver, Mr Abebe, who at times resembles a pilot as we seem to fly over the bumpy terrain in the plucky pick-up that is our steed for the day.

Impact

Asrat Afaw Amele

Against the scenic backdrop of the Ethiopian landscape racing by, with background music courtesy of Teddy Afro (whose politically charged songs, sweet voice and infectious rhythm have made him nothing short of a legend in his homeland), I take advantage of this long and winding road trip to interview Asrat, where his answers echo the whirlwind tour rushing by outside – from a description of the landscape he knows so well, and toils in every day – to the impact that this project has had on national scientists, the impacts on farmers’ lives, as well as impacts that are likely to come in the not-too-distant future.

We consider farmers our partners. We try to understand what farmers are looking for, what they like, and we try to include their interests in our breeding materials so that the breeding materials released by our institution start to get wider adoption.” – Asrat Asfaw Amele (pictured).

The rich Ethiopian landscape

Revolution, alliances & partnerships

Ethiopia’s rich history, as varied as its topographical landscape, has known its fair share of extreme rulers. Now it seems the new ‘regime’ calling the shots is climate change, whose ravaging effects are seen worldwide, and no less in the bean fields of Ethiopia. Asrat even pinpoints climate change as the greatest challenge for the next generation of bean researchers, saying, “The farmers’ growing environment may be modified or a new environment may be created. That could also be a challenge – a new pest population or new disease may come; so the challenge in the future may be to breed or develop varieties which adapt to the changing environment.”

Beans line up at Awassa Research Station

The revolutionaries needed to overthrow this ‘tyrant’, it seems, are those of the ‘triple alliance’ partnership, comprising: Ethiopia’s national scientists, researchers from the international science community including CGIAR Centres, and farmers. Firstly, with this approach, the science sector can understand farmers’ needs, which also has a reciprocal effect, as Asrat explains, “We consider farmers our partners. We try to understand what farmers are looking for, what they like, and we try to include their interests in our breeding materials so that the breeding materials released by our institution start are widely adopted.” Secondly, national and international science systems come together to work for a common goal – in Asrat’s words: “Now we’ve got the knowledge and we can speak a common language with people from advanced laboratories. It’s also brought us closer to international institutes like CIAT and other CG Centres – we work together, so they understand our system better and we understand how they function.” He adds, “We are getting technical backstopping from CGIAR Centres, so as a national partner we are doing work, and they are supplying germplasm. That’s the partnership that will continue in the future.”

The weapon used by this ‘revolutionary army’ is GCP’s double-barrelled approach which combines both traditional and molecular breeding practices and is proving to be effective in developing new, more productive bean varieties to combat drought and disease. Specifically of the TLI project, Asrat says, “It lets us know about molecular breeding, so it’s exposed us to new developments in science, especially in the application of molecular techniques and plant breeding.”

The ‘monster’, climate change, rears its ugly head only to be shot down expertly by Asrat and the mighty beans as he reveals, “A lot of farmers are growing our varieties, and, because of changing weather or instability, many people are starting to grow beans; beans are now becoming a major crop, especially in our mandate area.”

Capacity building …
At this stage, the major impact of the TLI beans component in Ethiopia has been on capacity building – both in terms of human resources and physical infrastructure, as Asrat illustrates, “In our breeding programme, capacity building has been an important aspect: scientists in our national system are being exposed to new technology, information, and training; we also have a full irrigation system in about 10 hectares of land, which will revolutionise our work.”

Magical bean diversity

… and on to farmers
By building on lessons learnt throughout this project, current impacts for the national science system will be translated into ‘real impacts’ in farmers’ fields in the near future. Indeed, Asrat hopes his future work will involve “getting the material into the hands of farmers, to see some impact or change, and to modernise and speed up breeding processes using markers developed by this project.”

Beanstalks: giant potential in Ethiopia

So the ‘magic beans’ of our story tell of a rich brew brimming with such potent ingredients as molecular breeding, capacity building, partnerships spanning continents and research systems, true teamwork with the farmers in the fields, and the drive to conquer the new challenge of a changing climate.

The impacts from the TLI project are the pot of gold at this rainbow’s end, showing that fairy tales do come true, where ‘magic beans’ put down roots and grow real shoots, and are not just ‘castles in the air’.
